y varies directly with x
means that
y = kx

when x = -4, y is y = 14
so
y = kx
turns into
14 = k*(-4)

solve for k and tell me what you get

-3.5, But I think Im wrong..

you're correct

so
y = kx
turns into
y = -3.5x

now they want to know the value of y when x = -6

so
y = -3.5x
y = -3.5(-6)
y = ???

21.

thank yoouuu!:))

nailed it

y varies directly with x
means what

y=kx

good

we're given x = 140 and y = 25
so
y = kx
becomes
25 = k*140

so k = ____
